tire issues

That's a real stumper, the only thing I can imagine that would change between runnibg and sitting would be the interface between the tire and wheel, causing it to leak by the bead seat. I know it would be a pain, but if break down the beads and reinstall them with some dishsoap in the bead area the soap (not soap and water just straight soap) this will help them seal in the bead area.
